除非首先在交互式窗口中调用smtplib,否则Python电子邮件脚本将失败

Question

我有一个通过邮件服务器发送电子邮件的脚本.该脚本仅在我import smtplib在交互式窗口中首先调用时才有效.否则,我收到以下错误:

ImportError:没有名为MIMEMultipart的模块

有人能帮我理解这种行为背后的根本原因吗？

import smtplib
from email.MIMEMultipart import MIMEMultipart
from email.MIMEBase import MIMEBase
from email.MIMEText import MIMEText
from email import Encoders
import os

# Fill in the necessary blanks here
gmail_user = "<your user name>"
gmail_pwd = "<your password>"

def mail(to, subject, text):
    msg = MIMEMultipart()

    msg['From'] = gmail_user
    msg['To'] = to
    msg['Subject'] = subject

    msg.attach(MIMEText(text))

    msg.attach(MIMEText(text))

    mailServer =smtplib.SMTP("smtp.gmail.com", 587)
    mailServer.ehlo()
    mailServer.starttls()
    mailServer.ehlo()
    mailServer.login(gmail_user, gmail_pwd)
    mailServer.sendmail(gmail_user, to, msg.as_string())
    mailServer.close()

mail("<recipient's email>",
     "Hello from python!",
     "This is an email sent with python")

可能是您的脚本命名为"email.py"还是您当前目录中有"email.py"(或"email.pyc"等)文件？
